I think a lot of people grab some books and watch some tutorials and they try to go it alone. There's nothing wrong with this and many of them even succeed with the effort of their own grit, but in my personal opinion I think having a teacher is the best possible resource you can have.
Someone to go back and forth with, someone to question, someone to explore and explain your ideas to who can better help you realize them. I'm suggesting find someone online, could be a friend, a mutual, or maybe go into development servers and try to find someone. Start small but build rapport. It's very useful to have someone who truly understands game design, and coding itself, in your corner. I can say with confidence that it helped me so I think it might help you too. Also if you're still in school see if they offer any classes in computer sciences.
